Google’s Driverless Car

Everyone’s fired up again. This time, however, the debate is moving in a direction that I can relate to. Here’ Megan McArdle (who has obviously been catching up on my blog archive):

Now I’m gloomy again.

Why? Not because of the technology. And not because of the regulation.  But because of the liability.  Self-driving cars represent a massive one–one that I’m not sure companies will take on.

Now, luckily, as many others are observing, a crazy tort system is somewhat unique here in the US and driverless cars need not multiply in the land of their birth.

My guess would be that promising-but-scary technology is more likely to be pioneered in a poorer country, since as people get wealthier they tend to become more risk averse and prioritize safety. But if something proves really useful and basically safe in some subset of countries, the pressure to change the rules elsewhere should become intense.

Good luck to Singapore or wherever but tweak US tort law? It is hard to describe how immense a task that is.

Putting these things onto roads full of human drivers means you probably don’t gain any macro benefits of more orderly roads. Handsfree driving is nice and all but is a few more hours of daily facebook for commuters going to spur Congress to the most fundamental overhaul of the legal system in generations?

For me it’s still filed with tacocopter and segways under ‘cool, technically viable idea: never going mainstream’.

2012 In Jury Verdicts

Some detail on the top three jury verdicts in 2012 (#1 is 716m, a big increase from last year):

The year’s massive top verdict [$716,500,000] was awarded against a convenience store for selling alcohol to a teenager who plowed into another vehicle, killing its occupant. The #2 verdict went to three workers burned in an explosion at a grain silo who were awarded more than $179 million against ConAgra Foods for failing to clean up stored wheat that became combustible.

More here.

By the way, this sort of thing is why insurance costs go up each year. By the link’s measure, the top verdicts are 10% higher than last year, which were 10% higher than the year before.

But even so, that 716m one is a bit ridiculous (from a convenience store?!). Here is a bit more detail:

How much the Garcia family actually will receive from the millions the jury awarded is uncertain, Gilbert said. But it’s important that the jury sent a message, he said.

“The amount of justice that this family got out of this verdict you can’t put a number on it,” Gilbert said.

Gilbert, I have little doubt, does not mean to “send a message” to the consumers of America to spend more on chocolate bars and bottled water because convenience stores raise prices to cover the increased cost of insurance.

The Placebo Effect is a Placebo

Here is a post debunking the “standard placebo narrative”: that there is a magical mind-over-matter process going on that heals of of our ills. In other words, the placebo effect is real.

What is measured in the placebo response includes things like reporting bias, or the desire of subjects to feel better, to please their doctor or the researcher, and to justify their prior decisions (to trust the doctor, take the treatment, enter the study, etc.). Begley fails to distinguish, in other words, between the pain that patients feel and the pain that they report. In studies we never know and cannot measure how much pain patients feel, only how much pain they report. Anything that would affect that reporting will also be lumped into “the placebo response” that is measured in the placebo arm of the study.

This is not quibbling. There is good reason to believe that reporting bias may be the major component of measured placebo effects.

And also very interesting is this study that finds no objective placebo effect. The benefits aren’t real.

In fact Begley did not mention the now famous (or infamous, I guess, depending on your perspective) study by Kaptchuk in which he studied both objective and subjective outcomes in asthma in response to active and placebo interventions. The results – there was a measured placebo response to subjective outcomes, but none for objective outcomes. Asthma is a condition susceptible to things like anxiety and expectation – so it provided a good opportunity to demonstrate objective improvement from placebo interventions, but showed none. This study, while very telling, does not fit the placebo narrative that journalists like to tell, and so is often absent from such articles or misinterpreted when present.

 

Moral Hazard is Corporate Kryptonite

In *Thinking Fast and Slow*, Kahneman relates a story told to him by Richard Thaler. It goes like this:

Once there was a gathering of executives from a large company. Each were asked about taking risky projects with a positive risk-adjusted expected value. The middle managers, who would be taking those risks, took a pass: put my job on the line? No thanks.

The CEO, on the other hand, wanted them to go for it. Kahneman’s explanation, which I like, is that the CEO benefits from diversification while the middle managers do not. A losing bet could cost them their job, but if they all make the bet, the CEO will take credit for the (very likely) subsequent growth.

There are some assumptions built into this assessment, though. Here is another story, from Arnold Kling:

Although I took no formal survey, I got the impression that most of them [middle managers] would agree with the following statements:

  • Corporations should give middle managers more freedom to take risk.
  • Corporations should be more willing to make mistakes and accept failure.
  • Corporations should offer more rewards and incentives for innovation.

…Suppose we re-phrase [these points] in terms of economic risk and reward. We might express them as:

  • Corporations should enable middle managers to make larger bets with corporate resources than is the case currently.
  • The downside risk of these bets should be borne more by the corporation and less by the middle manager than is the case currently.
  • More of the upside of these bets should accrue to middle managers than is the case currently.

…Middle managers understandably do not want the same degree of personal downside risk as entrepreneurs. However, in the absence of personal downside risk, the middle manager’s incentives would be skewed toward taking unjustifiable risks. Bureaucratic controls and limits on upside incentives may be an appropriate adaptation for correcting this potential bias.

As happens all the time when evaluating risks, we think statistical when we should be thinking behavioral. The risk changes depending on who is facing it and with what incentives (ie how hard they will work).

The point, I suppose, is that risk, which is rather an abstract sort of thing, in most businesses it is really a measure of the degree to which someone will be up to the task and can be controlled by highly skilled and motivated players. Real motivation, though, only comes when your ass is on the line. This is unacceptable for most people. Excellence, this line of thought goes, is driven by incentives (risk), and so is rare.

Bureaucracy is the blunt instrument that protects an organization from its most potent threat: risk without accountability. Moral hazard.

The result, as Arnold says here, is mediocrity. The base case for all organizations.

An Important New Model For Stock Pricing

We’re geeking out today.

Assets are priced differently and we don’t know why. Treasuries have different return characteristics than stocks, for example, and these characteristics change over time, even if the risks do not. Economists have a fancy term for this (of course): the stochastic discount factor. But what is it? CAPM says it is β, the correlation to overall market return. There’s a theory out there that the key is the “covariance between the asset’s return and aggregate consumption”*, which is one that I hadn’t heard of before.

This article points us to this paper that offers a new explanation: the liquidity needs of broker dealers, the firms that actually conduct trades.

These firms need to hold capital because their core activity, market making, is risky. But they also lever up that capital, naturally, and sometimes by a lot. There’s a cycle to how much leverage they hold, in some years leverage is high and in others it’s low (see the first link above for a graph). This somewhat coincides with the business cycle, but not as much as you might think.

Assets that only make money in high leverage cycles are worth less to broker dealers than assets less sensitive to leverage availability. When a leverage crunch comes along, survival depends on being able to liquidate at book value. So, for example, dealers have more demand for treasuries than B grade debt or equities, for example.

This demand from broker dealers means that assets that they want are going to have a lower return: dealer demand dominates the market. Assets they don’t want need a higher return to compensate for the lower demand. The relative return of these assets are going to vary with the leverage cycle. When leverage is abundant their prices soar. When leverage is scarce, they collapse.

It’s a pretty simple explanation and quite a good one, I think. What interesting about it is that it isn’t clear to me that there is any identifiable process that drives the leverage cycle, so forward information about sudden contractions and expansions of leverage can’t be easily priced into these assets. In other words, if we can’t predict when the leverage cycle reverses this insight won’t get priced in.

So if you could predict when the leverage cycle is going to switch, you could make a LOT of money.

*I might be missing something, but from a data standpoint, this idea strikes me as… inadequate. Under the expenditure approach of GDP calculation aggregate consumption is calculated by household survey and extrapolated to the economy as a whole. It’s hardly what I’d call hard data. And that’s for countries that have reliable household surveys.

Things Only Status Can Buy

The NJ Police union just gave Eli Manning, a resident of my town of Hoboken, a lifetime card of some sort. Here is the description from the article:

It is a highly coveted membership, and card-holders are treated with the utmost courtesy and respect by all in the law enforcement community.

So how it works is that you put in your car window to make sure you get treated with respect.

That’s nice.

Choose One: Flush Toilets or Facebook?

This is Kevin Kelly:

[Robert Gordon] is trying to argue that the consequences of the 2nd Industrial Revolution, which bought to common people electricity and plumbing, was far more important than the computers and internet which the 3rd Industrial Revolution has brought us. (Gordon’s 1st Industrial revolution was steam and railroads.) As evidence of this claim he offers this hypothetical choice between option A and option B.

With option A you are allowed to keep 2002 electronic technology, including your Windows 98 laptop accessing Amazon, and you can keep running water and indoor toilets; but you can’t use anything invented since 2002. Option B is that you get everything invented in the past decade right up to Facebook, Twitter, and the iPad, but you have to give up running water and indoor toilets. You have to haul the water into your dwelling and carry out the waste. Even at 3am on a rainy night, your only toilet option is a wet and perhaps muddy walk to the outhouse. Which option do you choose?

Gordon then goes on to say:

I have posed this imaginary choice to several audiences in speeches, and the usual reaction is a guffaw, a chuckle, because the preference for Option A is so obvious.

KK then tells us about some people who have Facebook but no flush toilets:

This area of Yunnan is consider one of the poorer areas in China, and the standard of living of the inhabitants here would be classified as “poor.”

Part of the reason is that these homes have no running water, no grid electricity, and no toilets. They don’t even have outhouses.

But the farmers and their children who live in these homes all have cell phones, and they have accounts on the Chinese versions of Twitter and Facebook, and recharge via solar panels…

Now, it isn’t clear that these people have had to make the choice between flush toilets and Facebook. But even if they had, I bet they’d be very tempted by Facebook. I spent a weekend in rural China many years ago and lived without flush toilets there. It isn’t so bad.

But only if I ignore externalities: indoor plumbing isn’t just about personal hygiene, it’s also about public health and disease control. Ask the rural Chinese if they’d choose Cholera and E Coli over Facebook you might get a different answer.

Considering their full benefits, I don’t think there’s any question that those older technologies are better in just about every conceivable way except one: they’re really expensive to install. That’s what’s cool about this (third by Kelly’s count) industrial revolution. Walk down to the shop and buy a phone and you’ve got Facebook. Not so easy to install plumbing in an entire town.

What Makes a Champion Bodybuilder? Tupperware

This video (hat tip) is about bodybuilder Kai Greene. Here is what Kai has to say about Bodybuilding…

A lot of bobybuilders go off track right here… I’m going to show you how it’s done… [first] you get yourself some Tupperware.

The point, as Kai drives home again and again and again is that he needs to eat every two hours every day. In order to do that he needs to always have food on him. In order to do that he has to cook it. Every day. To do that… well, let’s let Kai explain what it means to do that:

[you need to be able to] get up, cook you meals, pack them, have them with you and follow thorugh with eating them every two or three hours.

I’m not talking about focusing on how many grams of [protein, carbs, fat]… what I’m focusing on here is the development of character which speaks to your ability to follow through and start to string together days of efficient action on the very basic level.

…to have your food with you every day all day, in order for you to be able to eat on time and allows you to stay in an anabolic state. Now you start talking about the things that scientifically that can suppost cellular growth and muslce repair.

But if you are still working without the strength of character, without the ability to follow through, then all that complex converstaion about those sciences will mean very very little, will mean nothing to you.

…No one should stay over you: did you eat, are you on top of your schedule. Are you staying true to your path?

At the end of the day it’s just not important to everybody else. And if it’s more important to other people than it is you then there’s a large part of your better potential that will. not. be. tapped.

There’s often little that surprises in ‘inspirational’ videos: hero overcomes odds with hard work and perseverance and wins. The reality of high performance is of course that it demands an extraordinary tolerance of routine.

Put another way, I believe that success comes from an ability to do the shit that nobody else wants to do. Or refuses to learn how to do. Or thinks they can’t learn to do. But here’s the secret: apply time to most any problem and it will relent. Eventually. For problems with really juicy rewards, it takes longer than most people would tolerate.

That’s drive. It ain’t romantic. It is slow and really, truly, boring. Numbingly boring.

I find this idea… glorious.

The Best of Marginal Revolution

My favorite blog is Marginal Revolution, written by Tyler Cowen and Alex Tabarrok (both economists at George Mason University and the latter a Canadian!). Today they put out a list of their most popular posts of 2012, which contains a lot of great stuff. I’ll quote a few and paste a few awesome graphs below.

A Bet is a Tax on Bullshit ends with the money quote:

Overall, I am for betting because I am against bullshit. Bullshit is polluting our discourse and drowning the facts. A bet costs the bullshitter more than the non-bullshitter so the willingness to bet signals honest belief. A bet is a tax on bullshit; and it is a just tax, tribute paid by the bullshitters to those with genuine knowledge.

A simple theory of why so many smart young people go into finance, law, and consulting. A short piece; do read it.

Cowen goes at Robert Solow with both barrels in Robert Solow on Hayek and Friedman and MPS. Try this:

You can consider this essay a highly selective, error-laden, and disappointing account of a topic which could in fact use more serious scrutiny….

And Solow wonders why the Mont Pelerin Society and monetarism were needed. Solow should have started his piece with a sentence like “Milton Friedman was not right about everything, but most of his criticisms of my earlier views have been upheld by subsequent economic theory and practice….”

In Firefighters Don’t Fight Fires, we don’t even need quotes. We only need the graphs:

All in all, a great year from some of the best in the blogging biz.

Learn from Ndamukong Suh’s Bad Attitude

“Yeah, we’re loaded,” the player said, exhaling after Detroit (4-8) lost its fourth consecutive game and third by four points or less. “But we have a couple of guys who don’t understand what it takes to win. Just making a couple of plays and thinking that makes you great … sometimes you want to just shake some of these guys and say, ‘Don’t you get it?'”

Anybody in particular?

“Ndamukong [Suh] would be first.”

More here.

Ever made a good point in a meeting? Answered a tough question in class? What did you do for the next few minutes? Sat around replaying your brilliance in your own mind is what, probably.

It’s common to view team situations as status competitions. Forget the goal for a sec, do they think I’m smart? Aren’t I the best looking person here? That joke I just made got a laugh, I bet everyone is thinking of how funny I am.

This focus on minutiae of individual interaction is incredibly destructive from a teamwork standpoint. It interrupts the most important characteristic of high performance: achieving ‘flow’. Flow is the mental state of perfect focus on the task at hand.

A lot of this has to do with how you define success. When am I allowed to gloat a bit, even privately? Selfishness notwithstanding, this can be a difficult thing to figure out. Here is a quote paraphrasing one of my favorite books in the world, The Mental ABCs of Pitching, I think about all the time:

Dorfman once approached Greg Maddux after a game and asked him how it went. Maddux said simply: “Fifty out of 73.” He’d thrown 73 pitches and executed 50. Nothing else was relevant.

We don’t know whether the Braves won that game. We don’t know how many strikeouts Maddux got or how many home runs were scored on him. There’s a beautiful purity to this evaluation: it strips away everything that Maddux doesn’t control. And Maddux doesn’t celebrate after a single well-thrown ball, like Suh is accused of doing. It is through the aggregation of successful execution that he succeeds.

But this also shows me that Greg Maddux isn’t a leader. A leader takes it upon himself to tackle, in addition to his own extremely difficult job, the hardest problem of all: collective performance.

Training, motivation, culture. Leadership is a separate skill, perhaps independent from individual performance. That’s why we have coaches and managers who can specialize in it.

But stars, like Greg Maddux and like Ndamukong Suh, have a special power: their individual achievements grant them very high status. Status that draws people to them, that grants them influence over others. High status makes leadership easier, probably, but still devilishly hard.

And for some, the gift of influence comes with an obligation to use it. This is the frustration from teammates who see the potential in Suh. And lament its waste.
